Diagnose

TREMATERRA & CLAUSI (2009) liefern in ihrer Erstbeschreibung eine Differenzialdiagnose gegenüber der weit verbreiteten und häufigen Pammene fasciana: "Externally the new species resembles some Pammene moths like P. fasciana. In male genitalia it is similar to P. fasciana, the differences are small, mainly in the size that is bigger in P. castanicola. Sacculus long with distinct caudal angle in P. castanicola; sacculus short, with rather distinct caudal angle in P. fasciana (Figs 5 and 8). Aedeagus distinctly narrow beyond middle in P. castanicola, ventral part of aedeagus with ventral prominence in P. fasciana (Figs 6 and 9); cornuti of deciduous type arranged in a patch in P. castanicola, cornuti of deciduous type arranged in a row in P. fasciana (Figs 7 and 10)."

CLAUSI et al. (2016) teilen in ihrem Abstract mit: "Pammene castanicola Trematerra & Clausi, 2009 was recently described from chestnut woods near Etna Vulcan, Sicily (Trematerra and Clausi 2009), and it is known only from the vicinity of the type locality. It is similar to Pammene fasciana in morphological and biological features, and it was previously misidentified as P. fasciana. We provide observations on the biology and larval development and present detailed descriptions and illustrations of the mature larva of P. castanicola, with comments on the differences between P. castanicola and P. fasciana.
